This vulnerability allows an attacker to execute code on the victims machine by sending messages containing links with arbitrary protocols. The victim has to interact with the link and sees the URL that is opened. The issue was patched by implementing a helper function which checks if the URL's protocol is common. If it is common, the URL will be opened externally. If not, the URL will not be opened and a warning appears for the user informing them that a probably insecure URL was blocked from being executed. The issue is patched in Wire 3.20.x. More technical details about exploitation are available in the linked advisory."}, {"lang": "es", "value": "En Wire versiones anteriores a 3.20.x, se usaba \"shell.openExternal\" sin comprobar la URL. Esta vulnerabilidad permite a un atacante ejecutar c\u00f3digo en la m\u00e1quina de la v\u00edctima mediante el env\u00edo de mensajes que contienen enlaces con protocolos arbitrarios. La v\u00edctima tiene que interactuar con el enlace y visualizar la URL que es abierta. El problema fue parcheado mediante la implementaci\u00f3n de una funci\u00f3n auxiliar que comprueba si el protocolo de la URL es com\u00fan. Si es com\u00fan, la URL ser\u00e1 abierta externamente. De lo contrario, la URL no ser\u00e1 abierta y aparecer\u00e1 una advertencia para el usuario inform\u00e1ndole que fue probablemente una URL no segura fue bloqueada de ser ejecutada. El problema est\u00e1 parcheado en Wire versiones 3.20.x. M\u00e1s detalles t\u00e9cnicos sobre la explotaci\u00f3n est\u00e1n disponibles en el aviso vinculado"}], "lastModified": "2020-10-28T16:38:44.317", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:a:wire:wire:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "6848687A-01EF-42DF-A478-3DC588AA0E71", "versionEndExcluding": "3.20.2934"}], "operator": "OR"}]}], "sourceIdentifier": "security-advisories@github.com"}
